Description of key information
o-terphenyl: not susceptible to photolysis
p-terphenyl: not susceptible to photolysis
m-terphenyl: DT50 = 140 days
Key value for chemical safety assessment
Additional information
Three terphenyl isomers were tested for direct photolysis with sunlight during a 29 day period. The o- and p-isomer showed no significant decrease in concentration after 29 days of sunlight exposure, indicating that they are not susceptible to direct aqueous photolysis by sunlight. For m-terphenyl the half-life was calculated to be 140 days.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
